It would be great to have a template/task which can be configured to have a t-minus date.
For example, If i am planning an event, and i need to have a venue in place 90 days out, food vendors 60, staff 30, i'd like to be able to put in a date for the project due date and the number of days before.
This would be especially helpful with events that have many sub projects/tasks, or a moving deadline, where the event is subject to a specific venue or person's availability, but work can still commence otherwise. and if the final date changes, all due dates would reflow based on the t-minus.
